MIL-STD-461/MIL-STD-704 Investigation

Industry has expressed concern that the electromagnetic emission limits of MIL-STD-461 are incompatible with the AC voltage waveform distortion limits of MIL-STD-704. Previous industry studies have attempted to establish a correlation between MIL-STD-704 and MIL-STD-461 limits, but lacked the comprehensive analyses/data required for a meaningful document comparison. This paper presents the Navy's on-going effort to investigate equipment compatibility with MIL-STD-461 and MIL-STD-704 limits and to establish a correlation between the limits of MIL-STD-461 and MIL-STD-704. A preliminary investigation was conducted to review the requirements, test methods, and measurement relationships of specifications MIL-STD-461, MIL-STD-462, MIL-STD-704, and MIL-STD-1399.
